What does ERP software development cost in India really include?
An ERP budget has five parts: building the modules, moving your existing data in, training staff, hosting, and support after go-live. A quote that shows only the first part will look as if it has “overrun” the moment migration and training begin.
ERP, enterprise resource planning, means one system where purchase, stock, production, sales and accounts share the same data, so a goods receipt updates stock, the supplier’s ledger and the cost of production at once. For an SME the payoff is fewer reconciliations: no more matching the stores register with the accounts team’s Excel with the production supervisor’s notebook.
The build is priced module by module, because each module has its own screens, rules and reports. Migration is priced by how clean your data is. Training depends on how many departments go live and how comfortable staff are with computers. Hosting depends on users and data volume. Support depends on how much change you expect after launch.
With us, phase one starts at ₹60,000 and usually covers inventory, purchase and sales for one location, including GST invoices. Everything else is layered on in later phases, each quoted separately after the previous one is in daily use.
Custom ERP vs off-the-shelf ERP: which costs less for an Indian SME?
Off-the-shelf ERP usually costs less in the first year; custom ERP often costs less over five years when your user count is growing or your process is unusual. The right answer comes from adding up both over the same period, not from comparing the first invoice.
Packaged ERPs, whether licensed products or open-source systems like Odoo and ERPNext, come with years of features built in: accounting, multi-currency, standard manufacturing flows, hundreds of reports. If your business runs the way those systems expect, implementation is mostly configuration and training, and you benefit from updates the vendor makes.
The costs appear in three places. Licences are charged per user and sometimes per module, every year. Customisation to fit your shop floor is charged by the implementation partner and may need rework at each version upgrade. And staff often keep side spreadsheets for whatever the system does not handle, which is a hidden cost in time and errors.
A custom ERP flips this. You pay more for the build of each module, but nothing per user, and the system follows your process rather than the other way round. You also own the code and database outright.
If an open-source ERP is on your shortlist, compare ERPNext implementation and Odoo implementation cost in India before deciding.
Per-user licence fees vs a one-time build: the five-year view
Work out the five-year cost of both routes with the same user count and the same modules; the crossover point is usually where the decision becomes obvious.
For licensed ERP, list the users who need access today and in three years: stores, purchase, production supervisors, sales, accounts, management. Multiply each year’s user count by the per-user annual fee, add fees for extra modules such as manufacturing or payroll, add the implementation and customisation fee, and add any annual support charge from the partner.
For custom ERP, add the build cost for each phase you will need, cloud hosting for five years, and maintenance after the free period. Include the cost of adding features later, because you will; with licensed ERP those arrive with updates, with custom ERP you pay for them when you ask.
Then look beyond the totals. How many of your staff will realistically use the system? Licensed ERPs push businesses to share logins to save fees, which destroys the audit trail. Does the packaged ERP handle your costing method, your job-work flow, your dealer schemes? If not, add the customisation. Is there a date by which you must go live, such as a new financial year? Packaged systems may get you there faster.
How much does an inventory module add to ERP cost?
Inventory is the foundation module and sits in almost every phase one. Its cost depends on how you identify stock, how many locations you have and how strict valuation needs to be.
The simple version tracks items by quantity in one store, with receipts, issues and a reorder level. It gets heavier with each of these: several godowns or bins, units of measure that convert (bought in kilograms, issued in pieces), batch or lot numbers, expiry dates, serial numbers for machines or electronics, barcode or QR labels, and valuation methods your accountant specifies.
Physical stock counting is often forgotten in quotes. A good inventory module lets you freeze a location, count with a phone, and post differences with approval, so the opening stock you migrate stays reliable in month three.
We ask two questions early. How do your staff identify an item today: by name, code or photo? And how often does stock go missing between the register and reality? The answers shape the design more than any feature list.
For standalone stock systems without the rest of an ERP, see inventory management software.
Purchase module: indents, POs and supplier bills
A purchase module turns scattered requests and phone orders into a trail: someone raises an indent, purchase compares quotations, a purchase order goes out, stores receive against it and accounts match the supplier’s bill to what actually arrived. Cost rises with approval layers and quality checks.
The light version handles purchase orders and goods receipt notes. The fuller version adds indents from departments, approval limits by amount or category, supplier rate comparison, partial receipts, rejected quantity with debit notes, and three-way matching of order, receipt and bill.
For manufacturers, purchase links tightly to production. When a work order is planned, the ERP can show which raw materials fall short and suggest indents, which is where the real saving appears: fewer emergency purchases at poor rates, less excess stock blocking cash.
Supplier-facing features, such as a portal where vendors see open orders and upload invoices, are a separate line. They pay off when you have many regular suppliers and your purchase team spends hours on follow-up calls.
Production and BOM: the module that decides manufacturing ERP cost
Production is usually the most expensive module for a manufacturer, because every factory runs differently. Its cost depends on how many levels your bills of materials have, whether you work to order or to stock, and how much work goes to outside job workers.
The core is a bill of materials for each product, a work order that issues materials to the floor, and a receipt of finished goods with scrap recorded. Heavier needs include multi-level BOMs for assemblies, routing through several operations or machines, job work where material leaves your premises and returns processed, by-products, and costing that rolls up material, labour and overheads.
Shop-floor data entry is the weak point to plan for: a supervisor asked to type a whole shift into a desktop at the end of the day will fall behind. We design simple phone or tablet screens for output, rejection and downtime entries, sometimes with QR codes on job cards, so data arrives while it is still accurate.
Because production is so specific, we recommend it as phase two, after inventory and purchase are stable and your item masters are clean. That order also reduces the cost, since production depends on data those earlier modules create.
Sales, dispatch and GST accounting in an ERP
Sales and dispatch generate the documents your customers and the GST system see, so accuracy matters more than features. The module covers quotations, sales orders, dispatch, delivery challans and GST invoices, and for eligible businesses, e-invoices.
E-invoicing is a real cost driver. Under GST rules, businesses whose aggregate annual turnover has crossed ₹5 crore in any year must generate e-invoices for B2B supplies through the Invoice Registration Portal, and since 1 April 2025 businesses with turnover of ₹10 crore or more must report each invoice within 30 days of its date. An ERP for such a business needs the e-invoice integration built and tested; for a smaller one it can wait.
On the accounting side, you have two options. Keep your existing accounting software and push vouchers from the ERP into it, which accountants often prefer. Or use accounting inside the ERP, with ledgers, receivables, payables and GST reports. The first is quicker to build; the second removes a sync but needs your accountant’s full involvement in design.
Confirm your GST obligations with your chartered accountant; we build what they specify.
Why does ERP accounting need an audit trail in India?
If your company keeps its books of account in software, the Ministry of Corporate Affairs requires that software to record an audit trail. Since 1 April 2023, under Rule 3(1) of the Companies (Accounts) Rules, 2014, companies must use accounting software that records an audit trail of every transaction, creates an edit log of each change with the date, and does not allow the audit trail to be disabled.
For an ERP that holds accounting data, this is a design requirement, not an add-on. Every create, edit and delete on financial records must be logged with the user and timestamp, and the log must be protected from being switched off or quietly purged. It also affects cost: the logging must cover every module that touches the books, including purchase bills and sales invoices, not just the ledger screens.
We build audit logs into ERP modules by default, because even businesses outside the rule benefit from knowing who changed a rate, a stock quantity or a customer’s credit limit. What we do not do is certify compliance; your auditor decides whether the setup meets the rule for your company.
Should HR, attendance and payroll be part of your ERP?
Include attendance in the ERP when production costing or shift planning depends on it; keep payroll in a specialised tool or with your payroll consultant when statutory calculations are the main concern. Many SMEs do a mix.
Attendance is simple to connect: most biometric devices export punches that the ERP can import, and shifts, overtime and contract labour can then be linked to production output. That gives owners something valuable: labour cost per unit, by shift or by product.
Payroll is a different animal. Provident fund, ESI, professional tax and state labour rules change, and errors are costly. Building payroll is possible, and we have a separate guide on payroll software for factories, but it adds meaningful cost and needs sign-off from whoever handles your statutory filings.
A common middle path: the ERP handles attendance, overtime and contractor headcount, then exports a clean sheet that your payroll consultant or payroll tool processes. You get the operational data without owning the statutory risk.
How much does ERP data migration from Excel or Tally cost?
Migration cost depends on the state of your data, not its size. A clean item list with consistent codes imports quickly; five years of spreadsheets where the same bolt appears under four names needs cleaning first, and that is the slowest part of many ERP projects.
We migrate in layers. Masters first: items with units and HSN codes, customers, suppliers, bills of materials, employees. Then opening balances: stock by location as of the go-live date, customer and supplier outstanding, open purchase and sales orders. Historical transactions are brought in only if you really need them in the new system; often a read-only archive of old data is cheaper and just as useful.
From accounting software, masters and balances can usually be exported to spreadsheets and then mapped. From older custom software, we read the database directly where access is possible.
Your team’s time is part of the cost. Someone who knows the items must review the cleaned list, and someone must do a physical stock count close to go-live. We schedule these tasks in the project plan so they are not squeezed in at the end.
If your ERP journey starts from spreadsheets, our page on converting Excel to software shows how we map sheets to modules.
How long does ERP development take, and why go live in phases?
Each phase takes roughly 6–12 weeks with us, and a full ERP for a manufacturer is usually two to four phases. Phasing is not only about budget; it is the most reliable way to get staff to actually use the system.
A typical plan: phase one brings inventory, purchase and sales with GST invoices live in the stores and sales office. Once staff enter every transaction in the ERP and reports match physical stock, phase two adds production and BOMs on the shop floor. Phase three connects accounting, attendance and dashboards. Later phases add dealer portals, field apps or a second plant.
Within each phase, go-live is by department, often starting on the first day of a month so opening balances are clean. For the first weeks, key reports are checked against the old method, and we fix gaps quickly while the free support period is running.
Big-bang launches, where every department switches on the same day, look faster on paper. In practice they overload everyone at once, and when something goes wrong it is hard to tell where. The phased route spreads the same work over more weeks, and any problem surfaces in one department, where it is easy to trace.
What is an ERP AMC and what should the yearly cost cover?
An AMC, annual maintenance contract, is how many ERP vendors in India charge for yearly support, often as a percentage of licence or implementation value. Whatever the name, what matters is what it covers.
A useful AMC or maintenance plan includes security and dependency updates, monitoring and backups, fixing defects, small changes such as a new report column or a revised invoice format, and help for staff when something looks wrong. It usually excludes new modules, major process changes and on-site visits, which are quoted separately.
With us, every go-live comes with two months of free support. After that, maintenance starts from ₹8,000/mo per month if you want it, and the scope is agreed in writing in your quote. Because you own the code and cloud account, you are never locked into our support; your own IT staff or another developer can take over using the handover documentation.
Before signing any AMC, ask three things: what response you can expect for a stopped dispatch versus a cosmetic issue, whether version upgrades are included, and what happens to your data if you stop paying.
Odoo, ERPNext or fully custom: choosing the build route
Choose an open-source ERP when most of your process fits its standard flows; choose fully custom when the core of your business, such as costing, job work or dealer schemes, does not. Both are legitimate, and the cost difference depends on how much customisation the packaged route would need.
Odoo and ERPNext give you accounting, inventory, purchase, sales and manufacturing out of the box, with active communities. The trade-offs are licensing tiers for some editions and features, the learning curve of their frameworks, and customisations that must be maintained through upgrades. We cover these in detail on Odoo vs ERPNext and ERPNext development.
A custom ERP, which we build on mainstream open-source web technology with PostgreSQL, starts leaner. It contains only your modules, screens use your terms, and reports match what the owner already reads. It lacks the breadth of a packaged ERP on day one, which is why we phase it.
A practical test: list your ten most frequent transactions, then check how many a packaged ERP handles without customisation. Eight or more suggests packaged; five or fewer suggests custom.
Why ERP projects go over budget, and how to avoid it
Most ERP overruns come from decisions, not code: unclear ownership on the client side, unclean data discovered late, and scope growing during the build. Each can be prevented cheaply at the start.
- No internal owner: nominate one person with authority to answer questions and approve screens.
- Dirty masters: start item code cleaning in week one, not the week before go-live.
- Everything in phase one: keep phase one to the modules that cause the most pain today.
- Copying old paperwork exactly: use go-live as a chance to drop reports nobody reads.
- Skipping parallel checks: compare ERP stock and ledgers with the old method for the first weeks.
- Shared logins: they break the audit trail and hide training gaps.
- No written change process: price every new request as its own line before work starts.

Worked example: phasing an ERP for a small engineering unit
Say a hypothetical engineering unit in Rajkot makes pump components with about 45 staff, one plant, a stores room and a small sales office. Stock is in Excel, production in a supervisor’s register, and accounts in desktop accounting software. The owner cannot tell the real cost of any product.
Phase one would cover item masters with drawing numbers, stores with bin locations, purchase orders and goods receipt with inspection, and sales orders with GST invoices, starting from ₹60,000 and running about eight to ten weeks, depending on how quickly the item list is cleaned. Vouchers would flow to the existing accounting software, so the accountant keeps working as before.
Phase two would add two-level BOMs, work orders, material issue, machining sent to outside job workers and finished goods receipt, with supervisors entering output on a tablet. Phase three would import biometric attendance, add product costing and give the owner a daily dashboard on the phone.
Each phase would get its own estimate after the previous one is in daily use. The unit never pays per user, and if in year three it opens a second plant, that becomes a new phase rather than a new licence negotiation.
ERP software development cost in India across industrial cities
What we charge does not vary by city, because the work is remote and priced by module. What varies is the industry mix, and with it the modules that matter most.
Engineering and casting units in Rajkot and brass-part makers in Jamnagar need drawing-wise items, job work and heat or lot numbers. Auto-component suppliers in Aurangabad, Nashik and Faridabad need schedules from large buyers, rejection tracking and dispatch against delivery windows. Chemical and engineering firms around Vadodara need batch records and quality certificates. Home-textile exporters in Karur and sports-goods makers in Jalandhar need order-wise production tracking, while lock and hardware units in Aligarh juggle many small job workers.
The project runs the same way everywhere: requirement calls, a screen-share walkthrough of your current registers, a module-wise estimate, staging links, and phase-by-phase go-live. We do not make site visits, so your team photographs or screen-shares the documents we need.
